Overview

• Nicholas Brock, 57, was convicted at Oxford Crown Court on September 16 of two counts of making threats to kill and was sentenced to one year on each count to run consecutively.
• The threats occurred at HMP Bullingdon on May 20 and October 9, 2024, targeting prison officer Christopher English and probation officer Saiqa Yasmin, with one incident sparked by a dispute over a jacket potato.
• Counter Terrorism Policing South East searched his Maidenhead home in March 2025 and seized deactivated firearms, a knuckle duster, swords, knives, and a sword disguised as a walking stick.
• Investigators reported he possessed racist videos, including footage from the Christchurch massacre, and collected Nazi-era militaria, indicating an entrenched extreme right-wing ideology.
• Detective Chief Superintendent Claire Finlay said Brock claimed contacts could reactivate seized weapons and that his behaviour was worsening as he neared release from a 2021 terrorism sentence.
